Coutinho and Insigne aiming to maintain hot streaks - Champions League in Opta numbers

Barcelona and Napoli will be hoping Philippe Coutinho and Lorenzo Insigne can maintain their fine form when the Champions League returns on Tuesday.

Coutinho has been scoring and setting up goals for fun in European club football's premier competition and will hope to prove decisive against Inter, while Insigne is aiming to score in a fifth straight home game against Paris Saint-Germain.

Borussia Dortmund travel to Atletico Madrid fresh from their 4-0 humbling of Diego Simeone's side two weeks ago, while free-scoring Liverpool travel to Red Star Belgrade.
